Should be same for eth1 and eth2 on r4 as there are same macs for both…(r3 is different in this manner where second sfp is connected to switch not sfp). Can you show output for eth2 for same state (only no sfp)? Afair i had fewer options for both when no sfp is connected…this is maybe driver bug (creating the mac with fewer options)
I didn’t make any speed settings, I left it on automatic. It looks like this:
It shows the same options for eth2
and eth1
when I remove the SFP module.
So, either the SFP module can’t deal with 2500Mb/s or a driver issue. Because according to the manufacturer it should support it.
